FDA Grants Orphan Drug Designation to Eidos Therapeutics’ Product Candidate, AG10, for Treatment of Transthyretin Amyloidosis
SAN FRANCISCO, Oct. 03, 2018 (GLOBE NEWSWIRE) -- Eidos Therapeutics, Inc. (Eidos) (Nasdaq:EIDX), a clinical stage biopharmaceutical company focused on addressing the large and growing unmet need in diseases caused by transthyretin (TTR) amyloidosis (ATTR), announced today that the U.S. Food and Drug Administration (FDA) has granted the company Orphan Drug Designation for AG10 for the treatment of ATTR.
TTR normally circulates in the blood as a four-part molecule or tetramer, but in ATTR the tetramer destabilizes and dissociates into individual monomers which aggregate as amyloid fibrils. AG10, Eidos’ lead product candidate, is designed to target ATTR at its source by stabilizing tetrameric TTR in the blood. Eidos is investigating AG10 for the treatment of ATTR cardiomyopathy (ATTR-CM) and ATTR polyneuropathy (ATTR-PN), both of which are progressive, fatal diseases. The company plans to initiate Phase 3 studies in each indication in the first half of 2019.
“The granting of Orphan Drug status to Eidos’ lead development candidate, AG10, for treating transthyretin amyloidosis is an important step forward for the product and our company,” said Jonathan Fox, M.D., Ph.D., president and chief medical officer of Eidos. “We believe that AG10 holds great promise as a disease-modifying therapy for patients with ATTR, and Orphan status will help us develop it as quickly as possible.”
Orphan Drug Designation provides incentives and support for the development of drugs for patients with rare diseases, specifically to drugs that are intended for the treatment of diseases or conditions that affect fewer than 200,000 people in the United States. Orphan Drug Designation provides certain benefits, including seven years of market exclusivity upon regulatory approval, exemption from FDA application user fees and tax credits for qualified clinical trial expenses.
AG10 is an investigational, orally-administered small molecule designed to potently stabilize tetrameric transthyretin, or TTR, thereby halting at its outset the series of molecular events that give rise to amyloidosis, or ATTR. AG10 is currently being examined in a Phase 2 clinical trial in patients with ATTR cardiomyopathy. Top-line results from this trial are expected to be reported by the end of 2018.
AG10 was designed to mimic a naturally-occurring variant of the TTR gene (T119M) that is considered a “rescue mutation” because it has been shown to prevent ATTR in individuals carrying pathogenic, or disease-causing, mutations in the TTR gene. To our knowledge, AG10 is the only TTR stabilizer in development that has been observed to mimic the “super-stabilizing” properties of this rescue mutation.
